Over its long history, the island of Corsica has experienced the inundation of many cultures through successive invasions and occupations by Goths, Vandals, Etruscans, Phoenicians, Punics, Genoese, Romans, and Greeks. Each left its mark in one way or another. Ancient megaliths, twelfth-century Roman churches, fifteenth-century Genoese towers, Roman roads, all these and more can be found in Corsica. 

The best representation of stone "alignments" on Corsica are to be found in Sartene. They are intriguing curiosities of Corsica's ancient societies, though little is known about their history or function. It has been theorized that they served perhaps some religious or processional purpose. 

One of the first fortresses built on Corsica (though now in ruin) is in Tappa, dating back to 1,900 B.C. The sheer history of it, though, makes a visit there worthwhile. Other fortresses dot the landscape, especially near the coastline.  

By the end of the 6th century, the Roman Catholic Church owned a lot of land in Corsica. This led to the building of churches and smaller chapels. Though many are in ruin today, several still stand. Bell towers, like one in San Giovani de Cabrini, can be found, and are worth visiting. Within the walls of the San Giovani de Cabrini are frescoes dating back to the 1450s.  

Not all the architecture in Corsica is ancient, however. A good example of Corsica's architectural modernity can be found at Universita di Corsica Pascal Paoli, in Corte, so named in honor of the man considered the "father of Corsica."
